WRITING DESK OR TABLE.

SPECIFICATION forming part of Letters Patent No. 525,183, dated August28,1894.

Application filed May 19, 1894.

To all whom it may concern;-

Be it known that we, CHRISTIAN BORM and LUDWIG BORM, subjects of theEmperor of Germany, both residing at Hamburg, in the German Empire, haveinvented a new and useful Improvement in Writing Desks or Tables, ofwhich the following is a specification.

This invention relates to writing tables, desks and the like, having atop plate or tablet to be used for writing purposes, which tablet whennot in use can be placed in the interior of the piece of furniture ordesk which may be constructed in box form, said tablet by a turning overmotion imparted to the cover of the box, filling up the aperture left bythe cover and being brought into its proper position for writing upon.

The improvement further consists in the construction of said top plateor tablet whereby apart from its capability of being displaced in anupward and downward direction, it may be adjusted at an inclination tothe horizontal plane and likewise displaced forward and backward, by theaid of a simple mechanism.

Referring to the drawings which form a part of this specification,Figure 1 shows a vertical section taken from back to front of the boxshaped part of a writing table embodying our invention, in its conditionwhen closed or not in use. Fig. 2 represents a vertical cross section inline a: a; of Fig. 1. Figs. 3 and 4 represent sectional viewscorresponding with Figs. 1 and 2 respectively but showing the cover openand the writing tablet raised. Fig. 5 represents a plan viewcorresponding with Fig. 3 but having part of the writing tablet removed.Figs. 6 and 7 are sectional views corresponding with Fig. 3, except thatthe writing tablet is shown in different inclined positions. Figs. 8, 9,10, and 11 illustrate some details of the mechanism.

Similar letters of reference designate corresponding parts in all thefigures.

A represent the body of a writing table or desk constructed in boxshape, provided with a cover A hinged at a and serving to receivevarious utensils.

B is the movable writing plate or tablet which preferably by means of acaoutchouc Serial No. 511,739. (No model.)

against the base or bottom of the body or box A.

Inside the box A at both sides, supports 0 capable of turning uponhinges c, are pro vided, which by the aid of inclined pieces D arrangedat the rear end of the cover A, are raised out of their position shownin Fig. 1 into that shown in Fig. 4, when the cover is opened or turnedto the position'shown in Fig. 3.

Springs d attached to the cover serve to prevent the supports or ledgesC from being raised or turned too far aside and will, on the cover beingshut down, replace said ledges into their original position.

e (Figs. 1 and 3) is a helical spring attached to the back part of thebox A and pressing against a projection of the cover A, the said springcausing the cover A to rise or open slightly at the front end as soon asthe 010s ing spring f (see Fig. 8) has been'forced back by anappropriate key or the like.

To place the tablet B in an inclined position two hooked or loopedslides g (see particularly Figs. 9, 10,-and 11) are fitted to run inguides g at the under side of the tablet B, 'These can be hooked overbuttons or catches gaging of the hooked parts is done in analogousmanner.

Fig. 6 shows the tablet B in inclined position, its front end beingsupported on the supports 0. As in this case the front ledge m of thebox A might be in the way of the hand, an arrangement has been madewhereby the tablet B can be drawn forward on the complicated mechanismsare avoided thereinso that any failure of action is rendered practicallyimpossible. Should any disarrangement of the constituent parts occur,this can be easily remedied, since to all parts access can easily be hadand repairs be made by any persons having only ordinary skill.

Of prominent importance is the ready displaceability of the writingtablet into an inclined or other position.

What we claim as our invention is 1. The combination with the box Ahaving a hinged cover A and containing a movable writing tablet B, ofthe supports 0 hinged to the sides of the said box under the said tabletand the inclined pieces D attached to the said cover for lifting thesaid hinged supports and the tablet substantially as herein set forth.

2. The combination with the box having a hinged cover and the movablewriting tablet adapted to said box, of a button or catch on the insideof the cover, a hooked or looped slide fitted to guides on the underside of the tablet for engaging with said button or catch,
